Here in Florida, we have the opposite problem. The local governments encourage us to capture rainwater because we have heavy rains and very heavy runoff. Building and maintaining drainage ditches and retention ponds to handle this runoff is expensive and takes up a lot of land. Anything to slow or decrease the runoff is welcome.
I have eight 50 to 60 gallon each rain barrels around my property.
By the way, the satellite dish is a great idea for capturing rain water some distance from a building.
I've been looking for a smaller dish to cover with aluminum foil and convert to a solar oven. You could probably weld with a 9 foot dish
